AI Summary

Addressing the urban-rural broadband divide and the need to validate frontier wireless applications—such as remote agricultural machinery operation—in rural environments. Method: We established the ARA Wireless Living Lab, a large-scale heterogeneous real-world testbed spanning over 30 km of rural terrain. It introduces the world’s first long-distance, high-throughput integrated terrestrial x-haul/access and LEO satellite networking architecture, coupled with a BYOD-enabled, end-to-end programmable wireless-computing-fiber co-design framework. Leveraging SDR, Open RAN, programmable COTS hardware, edge-cloud orchestration, and satellite communications, the platform enables real-time, field-validated experimentation. Results: The lab demonstrates sub-100-ms latency for agricultural sensing and supports 100+ Mbps remote teleoperation of autonomous farm machinery. It delivers a reusable technical paradigm and empirical foundation for NextG network evolution and rural digital transformation.

Abstract

Addressing the broadband gap between rural and urban regions requires rural-focused wireless research and innovation. In the meantime, rural regions provide rich, diverse use cases of advanced wireless, and they offer unique real-world settings for piloting applications that advance the frontiers of wireless systems (e.g., teleoperation of ground and aerial vehicles). To fill the broadband gap and to leverage the unique opportunities that rural regions provide for piloting advanced wireless applications, we design and implement the ARA wireless living lab for research and innovation in rural wireless systems and their applications in precision agriculture, community services, and so on. ARA focuses on the unique community, application, and economic context of rural regions, and it features the first-of-its-kind, real-world deployment of long-distance, high-capacity terrestrial wireless x-haul and access platforms as well as low-earth-orbit (LEO) satellite communications platforms across a rural area of diameter over 30 km. With both software-defined radios and programmable COTS systems, and through effective orchestration of these wireless resources with fiber as well as compute resources embedded end-to-end across user equipment (UE), base stations (BS), edge, and cloud, including support for Bring Your Own Device (BYOD), ARA offers programmability, performance, robustness, and heterogeneity at the same time, thus enabling rural-focused co-evolution of wireless and applications while helping advance the frontiers of wireless systems in domains such as Open RAN, NextG, and agriculture applications.
